Problems solved by technology

[0002] At present, the patent has been applied for, the application number is CN02136360, and the announcement number is CN1471847. The title is the preparation method and application of feed additives for optimizing the meat quality of microbial breeding poultry. 1. Utilize the method of modern bioengineering mutation breeding to screen out Lactobacillus viridans, pure Lactobacillus saccharomyces, yeast, and Bacillus subtilis. After one expansion culture and two expansion cultures, the raw material cost of this process is high, and the process is complicated. Facilitate promotion in large-area chicken farms
[0003] Feed poultry refers to meat poultry that has been improved by hybridization, grows rapidly, and is fed with pure industrial intermediary materials. Although this kind of meat poultry is fed with comprehensive nutrition and rapid growth, the meat tastes poor and the cholesterol content is high. Excessive antibiotics and sterol substances are added to the feed, which will reduce the sensitivity of the human body to antibiotics and promote the precocious puberty of adolescents after ingestion, and there are many unsafe hidden dangers to human health
At present, in view of the above situation, the farms have adopted methods of adding flavoring agents, such as cloves, ginger, sweet pepper, etc., adding mulch, that is, orchard or vegetable garden soil, adding natural colorants, that is, carotene, lutein, etc., but also increased A large amount of labor and breeding costs failed to fundamentally solve the problem of meat quality optimization

Embodiment 1

[0042] The microbial poultry meat quality-optimized feed additive and its production method use bacteria strains that are optimized through screening and adopt a two-stage fermentation process, which includes the following steps:

[0043] The first step, the breeding and production of strains:

[0044] (1) Bacillus licheniformis, Lactobacillus plantarum, and Lactobacillus casei provided by the Culture Preservation Center of the Ministry of Agriculture are used to subculture through nutrient agar medium, and Saccharomyces cerevisiae is subcultured through starch medium to select and breed fast growth and strong colonies For strains with obvious characteristics, the strains should be preserved at a temperature of 0°C-4°C;

[0045] Nutrient agar medium: beef extract 3g, peptone 10g, NaCl 5g, agar 15-20g, water 1000ml, pH7.0-7.2, sterilized at 121°C for 20min;

[0046] Starch medium: peptone 10g, NaCl 5g, beef extract 5g, soluble starch 2g, distilled water 1000ml, agar 15-20g, st...

Embodiment 2

[0062] The first step. Breeding and production of strains: same as Example 1;

[0063] Step 2. First Stage Fermentation

[0064] (1), Bacillus licheniformis, Lactobacillus plantarum, Lactobacillus casei, Saccharomyces cerevisiae are respectively inoculated in the culture medium through steam sterilization according to the ratio of 40%, 15%, 10%, 35%, stirring speed 220r / min, the culture temperature was 35°C, the ventilation rate was 1:0.6, and after 24 hours of fermentation time, the compound bacterial agent expansion culture solution was obtained;

[0065] Weigh the culture medium according to the following weight percentage:

[0066] 2.5% soybean meal powder, 0.3% urea, 0.8% ammonium sulfate, 2.3% yeast powder, 1.2% corn steep liquor,

[0067] Corn flour 3.5%, molasses 1.5%, sodium carbonate 0.1%, magnesium phosphate 0.7%, sterile water 87.1%;

[0068] (2), inoculate the compound bacterial agent expansion culture solution in the substratum, the ratio is: strain expansion...

Abstract

The invention relates to a microbe cultivated poultry meat optimization feedstuff additive, which is characterized in that the invention takes optimized and treated compound microbes cereal crop byproducts as main culture medium and is produced by two stages of liquid expansion and solid fermentation. All bacteria types are addible bacteria allowed in 658 bulletin launched by Department of Agriculture, the liquid compound cultivation method of bacteria can be used to cultivate acquired bacteria in the same liquid medium, then the product can contain rich immune polypeptide, antioxidants and various vitamins, trace element chelate compound, active fungoid amylose, saponin, triterpene saponin and other substances that clean the free radical in animal body and significantly increase fat growth and inosinic acid content of poultry and improve the meat quality. The product has no toxin and residue with convenience use, and is the new feedstuff additive with safety and high efficiency.

Description

Technical field: [0001] The invention relates to a feed additive for optimizing the meat quality of microbial cultured poultry and a production method thereof.
